I can't click on any Unreal 4 UI such as Save or Settings

Hi
I am unable to use Unreal due to the buttons not being clickable for me. The little animation to show an actual button press shows, but menu’s don’t open. I can’t save, open ‘File/Edit/Window’ etc. This was on 4.12, so I upgraded to 4.16 but it is still happening. Please suggest fixes. I can’t open menus, click the scaling/size selections, open content browser etc… it’s horrible! Thank you

I have the exact same problem since about a week… Can’t click on “File/Edit/Window” and some of the popup elements do not show up…
I have this problem on any versions of Unreal (4.12 to 4.15)
Any help ?

Had this problem too. I was working with 4.13, 2 days ago I get an update (Windows 10) and now can’t select ANYTHING in the engine view-port. I did however manage to load 4.16 and get it to work, but so much stuff was done with my previous version I’d rather not re-do all of it…

Hopefully someone can help us.

Edit: Found issue here. This will work if you prefer not to remove windows 10 update.
